HY-GUARD™ is a advanced, maintenance-free hydrogen monitoring system specifically designed to address critical safety issues in standby battery installations. It is the industry's first hydrogen sensor designed for most battery applications. By utilising H2scan's field-proven, industry-leading sensor technology , delivers HY-GUARD™ true security guarantee through continuous self-calibration , which eliminates false alarms and the need for calibration gases or site visits. It helps organisations meet standards such as IFC and NFPA 855.
Characteristics
- Continuous Self-calibration: Performed every 12 hours during the long life of the sensor. This process verifies the performance of the sensor and provides warnings if the sensor performance degrades. No calibration gases, bump tests or site visits needed.
- Superior sensor performance: Uses proven sensor technology developed over 20 years in grid and power applications. Eliminates drift, false alarms and premature failures common in catalytic and metal oxide sensors.
- Zero Maintenance: Long sensor life and no calibration required over the life of the instrument.
- Flexible communication options: Includes dry, potential-free contact output for Alarm 1% H₂ and Alarm 2% H₂, and 4-20 mA analogue and Modbus RTU (RS-485).
- Power supply flexibility: Supports both AC and DC inputs. Uses AC as primary source by default, but automatically switch to DC in case of AC failure if powered by separate sources.
- Physical Design: All-in-one integrated, compact solution that eliminates the need for external modules, redundant cabling and complex pipework. Has a simple ”pull-apart design which simplifies installation, maintenance and bump testing.
- Alarms and indicators: Has a built-in buzzer on 83 db wide 3 ft.
Advantages
- True Safety Guarantee: HY-GUARD™ self-verification eliminates false security through continuous self-checking.
- Zero Maintenance: Long sensor life and no calibration required during the life of the instrument.
- Flexible configuration: Modular design allows selection of necessary functions, ranging from relay outputs to advanced communication protocols.
- Superior Reliability: Proven sensor technology without the drift, false alarms and premature failures common in catalytic and metal oxide sensors.
- Standards-driven development: Designed to meet stringent fire codes, including NFPA 855, the global standard for energy storage safety.
